Problem Analysis

Igor wanted to buy 6 notebooks but he was short of 40 tenge. So, he bought 5 notebooks and had 50 tenge left. We need to find the price of a notebook.

Solution

Let's assume the price of each notebook is x tenge.

According to the problem, Igor wanted to buy 6 notebooks but was short of 40 tenge. This means that the total cost of 6 notebooks is 6x tenge, and Igor had 40 tenge less than that.

So, we can write the equation: 6x - 40 = 5x.

Next, the problem states that Igor bought 5 notebooks and had 50 tenge left. This means that the total cost of 5 notebooks is 5x tenge, and Igor had an additional 50 tenge.

So, we can write the equation: 5x + 50 = 5x.

However, we can see that the equation 5x + 50 = 5x doesn't make sense because it implies that 50 = 0. This means that there is no solution to the problem as stated.

Therefore, we cannot determine the price of a notebook based on the given information.
